Thin Lenses

Objective

The purpose of this experiment is to obtain focal lengths of convex and concave lenses. [Thin Lens Equation: (1/do)+(1/di)=(1/f)] You will also learn the concept of magnification. [The Magnification Equation: (hi/ho)= -(di/do)]

Preparation & Warning

  • Please preview how to use a caliper and measure an object height (in the last page of the data sheet).
